Question

I have a question, i want to make some search page, and it needs a get variable to sort the results. So if someone enters the page without that GET variable, reload the page and make it appear, for example you enter http://www.myweb.com/search and automatically reloads and changes to http://www.myweb.com/search/?sort=ascending (because that variable is necessary) .

I hope you understand me, good bye

I think this will work for what you’re looking to do:

if (empty($_GET['sort'])) {
    header('Location: ' . $_SERVER['REQUEST_URI'] . '?sort=ascending');
    exit();
}
